Matching vendor offerings to service provider requirements

ABSTRACT

A method and system for using a graphical user interface for display and navigation of a three-dimensional navigational cube to assess vendors for meeting requirements of a service provider for deploying a selected service. A three-dimensional navigational cube configured to be navigated is generated and displayed. Mutually orthogonal axes of the navigational cube comprise subservices that the service provider must have to implement the selected service, vendors able to implement at least one of the subservices, and requirements stipulated by the service provider that are to be met for implementing the subservices. Selections sequentially received from a user include: one or more planar sections of the navigational cube, a vector of co-linear subcubes within one of the planar sections, and a single subcube within the selected vector which selects a vendor able to meet requirements for implementing the subservice for the selected single subcube.

This application is a continuation application claiming priority to Ser.No. 11/677,594, filed Feb. 22, 2007.

FIELD OF THE INVENTION

The invention relates to the field of consulting assessmentmethodologies and tools and in particular, the invention relates to anassessment methodology for matching vendor offerings to service providerrequirements.

BACKGROUND OF THE INVENTION

In order to offer a service to customers it is vital to understand whichtechnological requirements are essential for implementing the service.Once the technological requirements have been understood, vendors needto be located in order to provide the service provider with thecapabilities that are required to do the job.

Often, the process of finding suppliers, partners or vendors is alaborious task. For example, is it advisable to select the vendor thatwas previously used on a project and is trusted, even though they mightnot have the right skills for the job—or alternatively, should a vendorbe selected because the vendor is cheaper than another?

Thus, there are many factors to take into account when trying to deploya new service for the first time. Traditionally, the way to solve thisproblem has been to employ a number of consultants. A consultant mayrepresent a company (Company A) and hence the consultant will provideadvice and guidance with respect to the services and goods of thecompany that the consultant represents. However, the consultant'scompany may be ‘tied into’ particular third party products and services;i.e., the company has agreements with third parties for the supply ofgoods and services, and hence the third parties goods and services maynot give the flexibility and versatility required, but the price offeredby Company A may be very good. Hence a decision has to be made as towhether flexibility and versatility are to be sacrificed over price. Thesolution often is to find another consultant who will give arecommendation about their own company (company B) and thus the processstarts again until the end results is a number of recommendations bydifferent consultants with often conflicting views and products.

Hence, there is a need for a method and system for finding suppliers,partners, vendors, etc. that overcomes at least one of theaforementioned prevailing difficulties.

Referring to FIG. 1, a computer system 100 is shown in which embodimentsof the present invention may be implemented. The computer system 100 hasa processor, namely a central processing unit 101, with primary storagein the form of memory 102 (RAM and ROM). The memory 102 stores anoperating system 115, programs such as applications 116, and programinformation and data acted on or created by the programs. The programinformation includes the operating system code for the computer system100 and application code for applications running on the processor ofthe computer system 100. Secondary storage includes optical disk storage103 and magnetic disk storage 104. Data and program information can alsobe stored and accessed from the secondary storage. The RAM, ROM, andsecondary storage are computer readable memory units into which softwarecode portions may be stored, said software code portions capable ofbeing executed by the processor of the computer system 100 to performthe methods of the present invention.

The computer system 100 includes a network connection means 105 forinterfacing the computer system 100 to a network such as a local areanetwork (LAN) or the Internet. The computer system 100 may also haveother external source communication means such as a fax modem ortelephone connection.

The central processing unit 101 comprises inputs in the form of, asexamples, a keyboard 106, a mouse 107, voice input 108, and a scanner109 for inputting text, images, graphics or the like. Outputs from thecentral processing unit 100 may include a display means 110 (e.g., adisplay device such as a display on a computer screen), a printer 111,sound output 112, video output 113, etc.

In a distributed system, a computer system 100 as shown in FIG. 1 may beconnected via a network connection 105 to a server (not shown) on whichapplications may be run remotely from the central processing unit 101which is then referred to as a client system.

Applications may run on the computer system 100 from a storage means103, 104 or via a network connection 105 which may include spread sheetapplications, database applications and other storage and retrievalmechanisms.

FIG. 2 shows the components of an embodiment of the present invention.The present invention provides an assessment component 200 fordetermining a suitable match of vendors to requirements stipulated by aservice provider. The assessment component 200 may be located on thecomputer system 100 of FIG. 1 for accessing locally by the computersystem 100 or alternatively, the assessment component 200 may beinstalled on a server (not shown) for accessing the assessment componentvia the network connection 105. It should be understood that the termvendor is meant to comprise any party offering services and/ortechnology.

The assessment component 200 may be installed as part of an ‘add on’ toexisting consultancy tools or as part of an existing consultancy toolsuite.

The assessment component 200 comprises a number of subcomponents whichinterface and interact with each other in order to analyze a serviceprovider's requirements and to determine the most suitably matchedvendors. The subcomponents comprise a receiving component 205, aselector component 210, a visualization component 225, an assessmentengine 220, a first data store 215 comprising sets of engagements typesand a second data store 230 comprising the output of the assessmentcomponent 200 in the form of an assessment set. The data store 215 andthe data store 230 may each be in RAM, ROM, the optical disk storage103, the magnetic disk storage 104, etc. (see FIG. 1). Each of thesesubcomponents will now be explained in turn.

The receiving component 205 receives data inputs for populating the datastore 215. The data is in the form of data concerning types of services.Also, for each service the subservices required to implement the serviceand for each subservice, the vendors offering the subservice and theparticular capabilities of each of the vendors. For clarity it is to heunderstood that a vendor is any third party who provides services and/ortechnology. An example of the data structure is as follows in Table 1.

TABLE 1 Vendor and/or Service Subservices partner Capabilities Tripleplay ISP-portal Company A Supports Company B standard x Company CCompany D Mail services Company A Company B IPTV-portal Company DCompany C Video-on-demand Company A With a response Company B time of XCompany C number of Company D seconds Personal Video Company D Company ERecorder Company G Company B TV head-end Company H Company A Company E

This data is stored in the data store 215 for interfacing with theselector component 210. FIG. 3 also details the engagement type data asstored in the data store 215. FIG. 3 shows that for a digital mediaengagement type, the data store will store information regarding theservices 305 needed to deploy a digital media solution 300, thesuppliers and/or vendors 310 offering digital media solutions 300, andthe capabilities of each of the suppliers and/or vendors 315.

Returning to FIG. 2, the selector component 210 is a selecting functionwhich allows a user to select from a list, the type or solution theservice provider wishes to deploy. The user may be the service provideror one who is acting on behalf of the service provider. For example, theservice provider may be a telecommunication service provider wishing todeploy a triple play service; i.e., an integrated voice, video anddata-IP solution to their customers, or a service provider wishing todeploy a biometric solution (fingerprint or retina scanning andrecognition solution) to a specific customer base.

The selector component 210 receives the selection from the user andperforms a lookup in the data store to locate the subservices requiredto deploy the service and the vendors who are able to supply thesubservice. The user is also presented with the capabilities of thevendor's goods and services. Once the selector component 210 hasperformed a lookup in the data store 215 and retrieved the relevantinformation, a trigger is sent to the assessment engine 220 requestingthe assessment engine 220 to perform an assessment on the engagement set215.

The assessment engine 220 begins by displaying to the user via thevisualization component 225, a series of questions in order to gatherfacts about the user's business in order to perform a ‘Where-to-goassessment’. The purpose of the ‘where-to-go assessment’ is to workthrough each of the subservices associated with the requestor's servicethey wish to deploy in order to assess the requestor's current positionwith respect to the implementation of the subservice and where the userwishes to be with the subservice or technology according to theirstrategy and business propositions. For each subservice the user isasked to supply information about whether the business already has thesubservice. For example, if the subservice is an IPTV portal—the user isasked whether they already have an implemented IPTV portal. If theanswer is ‘no’, and this subservice is vital to the implementation ofthe user's triple play service—the assessment engine 220 assigns arating to the IPTV subservice of, for example, 2—indicating that this isa subservice that the user ‘must have’ in order to implement theservice. The assessment engine 220 performs this assessment for eachsubservice identified by the selector component 210. The output of theassessment is a list of ‘must have services and/or technologies’ and isstored in the assessment set data store 230.

The assessment engine 220 performs an impact assessment on each of theidentified ‘must have subservices and/or technologies’. The assessmentengine 220 uses a number of criteria to determine an assessment scorefor each ‘must have’ subservice. For example, the criteria may be asfollows: Investment; Operational costs; Involves more than one part(complex project management); Personnel; Complexity; Branding exposure;Value for customer; Assumed ROI (length); Customer demand (assumed).

Thus, for each ‘must have’ a determination is made as to what the impactof implementing the subservice would be on a specified criteria (e.g.,low, medium or high impact) as is shown for an example in Table 2 below.

TABLE 2 Criteria Impact Investment High Operational costs Medium Complexproject management High Personnel Medium Complexity Low Brandingexposure Medium Value for customer High Assumed ROI (length) LowCustomer demand (assumed) High

As a series of criterion is being assessed, it is noted that thedifferent criterion will have a different importance factor fordifferent requestors. Thus the assessment engine 220 determines aweighting factor indicative of the importance to the requestor of theassessment criteria. This is shown in the Table 3 below.

TABLE 3 Criteria Impact Weighting Investment High High Operational costsMedium Medium Complex project management High Low Personnel Medium HighComplexity Low Low Branding exposure Medium Low Value for customer HighHigh Assumed ROI (length) Low High Customer demand (assumed) High High

The assessment engine 220, for each assessed criteria, multiplies theimpact score by the weighting to derive an absolute score index. Theassessment engine 220 adds each of the absolute score indexes togetherto derive a total impact assessment score. The total impact assessmentscore is stored in the data store as part of the impact assessment 410.

Each Impact factor and Weighting factor in Table 3 has an associatednumerical value. For example, High, Medium, Low for the Impact factorsmay have have an associated numerical value of 3, 2, 1, respectively,and High, Medium, Low for the Weighting factors may have have anassociated numerical value of 5, 3, 1, respectively. For, the precedingexemplary numerical values of the Impact factors and the Weightingfactors, the total absolute scores are 15 (Investment), 6 (OperationalCosts), 3 (Complex project management), 10 (Personnel), 1 (Complexity),2 (Branding exposure), 15 (Value for customer), 5 (Assumed ROI), 15(Customer demand), and the total impact assessment score is 72.

The impact on the individual criteria (such as the individual impacts onthe impact criteria listed in Table 3) and the total impact assessmentscore each constitute a measure of impact on the specified criteria ofimplementing the subservice.

Using the above scoring system—the lower the total absolute score thebetter. However using a different scoring scheme it will be appreciatedby a person skilled in the art that other forms and variation of theabove can be contemplated without departing from the scope of theinvention.

The assessment engine 220 also performs an impact assessment on thepartners and vendors which the selection component 210 identified asoffering the identified subservices. For example, if the subservice isan IPTV portal, then company A, B and C may be identified as providersof an IPTV portal. For each identified supplier/vendor an impactassessment is performed by the assessment engine 220. Firstly, theassessment engine 220 performs a ‘where to go’ assessment and identifiesthe suppliers and/or vendors that the user wishes to provide their ‘musthave’ service. The selected preferred suppliers or vendors are added toa preference list and stored in the suppliers and vendors assessmentdata set in the data store 405.

The assessment engine 220 determines, via information received from theuser as specified by the service provider, a target assessment of anideal supplier and/or vendor; i.e. rating most important characteristicthat the service provider would like a vendor/supplier to have in termsof specified criteria.

An example of vendor targets is shown for specified vendor assessmentcriteria in the Table 4 below for the vendor denoted as Company A withrespect to the subservice of IPTV-portal.

Partner/Vendor Strategy

Subservice: IPTV-portal

Company: A

TABLE 4 Criteria Target Completeness of the service/delivery HighCompetence High Service and support High Price HighReputation/image/brand High References High Relations to client HighFuture presence High Standards and openness High

The assessment engine 220 proceeds to carry out an actual assessment ofeach potential vendor of the specific service or technology, for exampleIPTV, against the assigned rating of an ideal vendor. The actualassessment determines how far away the potential vendor is in reachingthe criterion with respect to the ‘must have’ service or technology. Theassessment engine 220 prompts the user, via the visualization component225, to enter a value against each criterion to indicate how far awaythe potential supplier/vendor is from the ideal supplier/vendor.

An example is shown in Table 5 below.

TABLE 5 Criteria Target Actual Completeness of the service/delivery HighHigh Competence High High Service and support High High Price HighMedium Reputation/image/brand High High References High Low Relations toclient High High Future presence High Low Standards and openness HighLow

Next, the assessment engine 220, via the visualization component 225,prompts the user to enter a weighting score for each of the criterion inorder to differentiate between each criterion and the partner/vendorbeing assessed. An example is shown in Table 6 below.

TABLE 6 Criteria Target Actual Weight Completeness of theservice/delivery High High Low Competence High High Low Service andsupport High High Medium Price High Medium High Reputation/image/brandHigh High Medium References High Low Low Relations to client High HighLow Future presence High Low Medium Standards and openness High LowMedium

Next, the assessment engine 220 determines an absolute score index thatreflects how well the supplier or vendor complies with the ideal partneror vendor and the assessed importance of each assessment criteria. TheTarget score, Actual score, and Weight of High, Medium, and Low in Table6 have associated numerical values. To determine the absolute scoreindex, the assessment engine 220 takes the actual score for eachassessment criterion and subtracts the actual score for each assessmentcriterion from the target score for each assessment criterion. Then, foreach score, the weight given to each assessment criterion is multipliedby the calculated score thus deriving an absolute score index of eachassessment criteria. This calculation may yield negative values for theabsolute score index if the assessed partner or vendor scores higherthan the target. For each vendor or supplier, the absolute score indexesof the assessment criteria are added together to determine a totalvendor assessment score which is stored for each vendor or supplier inthe vendors assessment set 405 of FIG. 4.

The absolute score indexes and the total vendor assessment score eachconstitute a measure of an extent to which each vendor is able to meetspecified targets for specified vendor assessment criteria pertaining toeach subservice.

Lastly, the assessment engine 220 assesses the requirements of each ofthe ‘must have service and/or technologies’. Most of these requirementswill be non-functional requirements represented by a single figure, forexample, a requirement that the service must support 10,000 users. Otherrequirements may be of a binary nature, for example, does the vendorsupport MPEG2—yes or no?

The requirements assessment is performed in two stages, firstly a‘where-to-go’ assessment is carried out by documenting the client'starget criterion—i.e. MPEG2 must be supported—yes or no? If the answeris determined as ‘yes’—the client's target criterion is given aweighting of ‘high’ to indicate that this is a must have technologyrequirement. Secondly, the client is asked to ‘weight’ the importance ofthe ‘must have’ technology requirement, for example, as a high, mediumor low importance. This two stage assessment is carried out for eachrequirement listed or selected via the client.

For example in Table 7.

TABLE 7 Target Requirement Score Target Weight Ref date MPEG2 2 2 2 CIO4Q No. of users or 1 10,000 3 CIO 4Q households

The final step is to set scores for each requirement and vendor. Foreach short listed vendor a score is provided representing this vendor'sactual capability. For example, if a particular vendor is able to meetthe requirement, the vendor is assigned a score of, for example, 2.However, if the vendor is only able to partially meet the requirements,the vendor will be assigned a score of, for example, 1 etc.

As previously explained, the weighting of for the target requirement maybe represented by a score in a simple ‘yes’ or ‘no’ format or it can bea non-functional requirement for example, the number of users perhousehold. For this reason these values cannot determine the bestpossible mix of services and partner or vendor for each requirement. Ifany assessments of these requirement drivers have been carried outbefore for the same service or technology in the same engagement set forthe same partner or vendor, the score can be reused by extracting themout of the assessment set. The assessed weights will normally not bereused as they typically will be specific for each client.

Finally the total requirement assessment score for each of theshort-listed vendors is as follows:Total requirement assessment score=score(i)*weight(i)wherein the integer i indexes the requirements and is stored for eachvendor or supplier in the requirements assessment set 415 of FIG. 4.

The output of the assessment tool is a list of vendors that meet therequestor's requirements. The list may be weighted to indicate a first,second and third match etc. This is stored in the requirementsassessment data set 415 as shown in FIG. 4.

The total requirements assessment score is a measure of an extent towhich each vendor is able to meet specified requirements for pertainingto each subservice.

Each of the impact assessments is stored in a data store 230. This isshown in FIG. 4, wherein the totality of the impact assessments form anassessment set comprising of each of the ‘where to go assessments’ 400,the impact assessments 410, the vendor assessments 405 and each of therequirements assessments 415.

A visualization component 225 provides navigational functionality in theform of a navigation cube as is shown with reference to FIG. 5. Thenavigation cube 500 provides a framework which enables a requester toload the requested information from the selector component 210 into thenavigation cube 500. The navigation cube 500 provides the ability tonavigate three dimensional data. This is shown by the three axis 505,510 and 515 of the navigation cube 500, namely vendors 510, services andtechnologies (i.e., subservices) 505 and requirements 520. The threeaxis forming in their totality the engagement set 215 for a requester'svalue proposition; i.e. their service or technology requirements.

The navigation cube 500 may be implemented in computer software andallows a user to manipulate and rotate the navigation cube 500 in manydifferent directions in order to view the engagement set data throughdifferent planes.

The navigation cube 500 allows all interrelated elements (i.e.,subcubes) of the navigation cube 500 to be visualized by using a chosencolor (i.e., green, blue red) as represented by differential shading asindicated in FIG. 5 (as well as in FIGS. 6-9), for example, blue forpartners and vendors, red for requirements and green for services andtechnologies.

The navigation cube 500 when loaded with an engagement set allows theviewing and inspection of the assessed numerical scores of eachcombination of services and technologies, partners and vendors andrequirements as calculated by the assessment component. Via thenavigation cube 500 is it easy to view and understand which vendorsprovide the most suitable match to the requestor's requirements.

Once the navigation cube 500 has been loaded with the engagement set andassessment set, various views can be selected by viewing individualplanes, vectors or single elements in order to inspect which vendorsupports specific services and technologies, as is shown with referenceto FIG. 6.

FIG. 6 shows a selected plane detailing the assessment results forcompany B. Here it is shown that there are many elements 600 which aretransparent and other elements 605 which are non-transparent (e.g., havecolored faces in FIG. 6). The transparent elements show there is norelevant data in which to populate the elements with and the coloredelements indicating the population of data with regards to the discreteelements. For example, the colored elements 605 show that company Bsupports and can provide IPTV-portal services, video-on-demand servicesand TV head end service. The transparent elements 600 indicate theservices and technologies which company B does not support or provide;i.e., ISP-portal, mail services and PVR. Each of these elements aredisplayed against the requirement drivers; i.e. the number of users perhousehold, availability, scalability, MPEG2, MPEG4 and WM9. Thereforewhen viewing the engagement and assessments sets through this plane ofthe navigation cube, one can see the company B can provide a TV head endwhich meets the requirements of number of users, availability,scalability, MPEG2, MPEG4 and WM9. However, when it comes to IPTVportals, company B can not provide an IP-TV portal meeting the MPEG4requirement.

The selected plane of FIG. 6 can be turned through various aspects toprovide easier viewing of certain aspects. In the example, of FIG. 7, itis clearly shown that company B only supports MPEG4 in their TV head-endoffering and not for the IPTV-portal of for their VoD offering.

A user may also select only one specific service or technology ofinterest which is being offered by a single partner or vendor and thus asingle vector can be viewed. Further, when selecting a single element,each of the assessed weightings can also be displayed.

FIGS. 8 and 9 shows a flow chart describing the operation steps of thenavigation cube 500.

In FIG. 8, at step 800, an engagement set is loaded into the navigationcube 500. The navigation cube 500 is exploded and labeled at step 805and as is shown at step 810. Once the navigation cube 500 is populatedand exploded, the user can select a number of different planes tonavigate through. For example, at step 815 the user can select a redplane (i.e., a Requirements plane) and navigate through the requirementdrivers for that particular engagement set at step 830. Alternatively atstep 820 and step 835, the user can navigate through a blue plane (i.e.,a Partners and Vendors plane). At step 825, the user can navigatethrough a green plane (i.e., a Services and Technologies plane).

Moving onto FIG. 9, at step 900, the user whilst navigating through theservices and technologies plane can navigate further and view a singlepartner and vendor plane showing all the interrelated elements (as shownin FIG. 7). Moving onto to step 905 and step 925, the user is also ableto select a vertical vector to view a single requirement across allservices and technologies. If the user does not wish to view a verticalvector, the user can instead at step 910 view a single service andtechnology across all requirements drivers. From this view, a singleelement representing a requirement driver can be selected and viewed asa single entity at step 915 and 920. Step 920 enables the user todisplay a single element of the vertical vector displayed at step 915(e.g., by selecting the single element with a selection device such asby clicking a mouse when navigating the navigational cube 500 of FIG.5), wherein the single element holds the total impact assessment score,the total vendor assessment score, and the total requirement assessmentscore.

Referring to FIG. 10, the process steps of an embodiment of the presentinvention are shown. At step 1000 and step 1005, the user selects thetype of service they wish to implement via the selector component 210.The assessment component 225, using the selected information performs alookup in an engagement type data store to retrieve the subservices thatare required to be implemented in order to deploy the service. For eachidentified subservice, the assessment component 225 locates a vendorwhich can supply the service and vendors capabilities. At step 1010, theassessment component 225 performs a ‘where-to-go’ assessment todetermine a set of ‘must have’ services and technologies. If theassessment component can not generate any ‘must have’ technologies andor services at determination 1015, control moves back to step 1000 andthe user is required to enter further information. However, if theassessment component can generate at least one ‘must have’, controlmoves to step 1020 and the assessment component performs an impactassessment in order to compute an absolute score index which is storedin the data store 230.

Next in steps 1025 and 1030 the assessment engine 225 performs awhere-to-go assessment on each vendor identified as offering one of the‘must have’ services or technologies in order at step 530. At step 1035a determination is made to identify whether any partner and/or vendorsprovide any ‘must have’ services or technologies. If the determinationis positive, control moves to step 1040 and the ‘where-to-go’requirements are calculated and weighted as explained previously andstored in the assessment set data store along with the othercalculations and weightings. At step 1050 a list is generated or thedata is loaded into the navigation cube detailing the partners andvendors whom are can meet the requestor's requirements.

While particular embodiments of the present invention have beendescribed herein for purposes of illustration, many modifications andchanges will become apparent to those skilled in the art. Accordingly,the appended claims are intended to encompass all such modifications andchanges as fall within the true spirit and scope of this invention.
